The expected maximum (derived from NED recession ># velocity) of typical SN Ia is well below (more than 1 mag) of the ># reported magnitude on Mar. 13.918, so the timely follow-up ># observations (spectroscopy, photometry) are extremely encouraged. The CfA team revealed that it is a type II supernova. The recession velocity deduced from the H-alpha emission peak (from the spectrum on the website*) is about 14000 km/s, which is consistent with the NED value. The SN can be a very luminous event, or the host galaxy has a peculiarly large proper motion relative to the Hubble flow. The apparent size of the galaxy seems large, so the latter possibility should be considered. * http://cfa-www.harvard.edu/cfa/oir/Research/supernova/spectra/sn2003bv-20030325.flm.gif SN 2003cq: In [vsnet-campaign-sn 593] (Apr. 1) >SN2003cq 20030314.0 <174:C ARB >SN2003cq 20030330.84 170:C ARB >SN2003cq 20030331.816 179:C Bol >SN2003cq 20030331.830 170:C ARB > ># SN 2003cq (11:56:14.17, +60:31:19.1 (J2000.0), offset = 32"E, 2"S) ># is hosted by NGC 3978, a face-on spiral (SABbc:) galaxy making a ># pair with 2' west NGC 3975.
